The device manager is a Control Panel applet in Microsoft Windows operating systems. It allows users to view and control the hardware attached to the computer. When a piece of hardware is not working, the offending hardware is highlighted for the user to deal with. The list of hardware can be sorted by various criteria. For each device, users can:
- Supply device drivers
- Enable or disable devices
- Tell Windows to ignore malfunctioning devices
- View other technical properties
Device Manager was introduced with Windows 95 and later added to Windows 2000. In NT-based versions, it is included as a Microsoft Management Console snap-in.
